DESCRIPTION:
A vulnerability has been discovered in concrete5, which can be
exploited by malicious people to conduct cross-site request forgery
attacks.

The application allows users to perform certain actions via HTTP
requests without making proper validity checks to verify the
requests. This can be exploited to e.g. add a scrapbook entry by
tricking a logged-in administrator into visiting a malicious web
site.

NOTE: This can further be exploited to perform script insertion
attacks.

The vulnerability is confirmed in version 5.4.1.1. Other versions may
also be affected.

SOLUTION:
Do not browse untrusted web sites or follow untrusted links while
being logged-in to the application.
